Research On Synthesis Process And Kinetic Equation Of ECH And TMAC In Microemulsion

Microemulsion is a high-dispersed and stabilized thermodynamic system, where the micells produced by dispersed phase are in nanometer size. Such especial micro-environment can affect chemical reaction, such as enhancing sensitivity of detected ions in analytical chemistry, producing high-pure particulates and nano materials in the synthesis of inorganic materials, protecting protein and altering the catalytic efficiency of enzyme, intensifying some reactions in liquid- liquid phase .The liquid-liquid bi-phase synthesis reaction of ECH and TMAC was processed in microemulsion,include seeking feasible projects and putting up the microemulsion. In model reaction, because of poor contact of two liquid reactants, synthesis reactions are restricted in liquid- liquid biphase. Microemulsion has large interface area between oil and water phases, which could improve the interface contact and strengthen the reaction. We process liquid-liquid diphase synthesis reaction in microemulsion and in non-microemulsion respectively, measuring and comparing every matter's molar quantity in different reaction time by combined analysis of LC and GC. The results proved that reaction rates in microemulsion are much higher than ones in non-microemulsion, the rational reason is the large interface area between oil and water in microemulsion, where the ions of reactants contact and react. In addition, surfactant's electrostatic effect plays an important role in enhancing the reaction rates. According to the change between every matter's molar quantity with time in different temperatures, we set up two kinetic equations of liquid-liquid biphase synthesis reaction of ECH and TMAC in microemulsion. Finally kinetic parameters are obtained and the theoretic model is established.
